Looking forward to the finished game. No idea why the player isn’t visible in the bottom room - I played it on the C64 core of Mega65 (which was ported from MiSTer).
Where there's a bug, there's a lazy programmer! 😉 We'll take this into account and fix it for the full release. Thanks for reporting it!
More like a lazy Viper. Sorry, your original demo works perfectly fine. I downloaded the very first "crack" from CSDB, which introduced this bug.
